12c: Extproc calls are not being released until listener is stopped and processes are killed

(Doc ID 2371611.1)

Last updated on MARCH 09, 2018

Applies to:

Oracle Net Services - Version 12.1.0.2 and later
Information in this document applies to any platform.

Symptoms

You may find that extproc calls through the LISTENER (not Dynamically spawned ones) are not being released.
This can result in excessive processes remaining on the Database Server.
Only solution is to stop the Listener and kill the processes that seem to be "stuck"


Changes

 This may be a new installation or an upgrade, containing SID_DESC information for Extproc rather than the default Extproc use via the Multithreaded Extproc Agent.
